Hertel 300-002010 Combo Drill Countersink Size 8 Solid Carbide

Product Description

The HERTEL 300-002010 is a solid carbide combo drill countersink designed to drill and countersink in a single pass. It carries a trade size of 8 with a 3/4-inch body diameter and a 5/16-inch drill point diameter. The drill point angle is 118 degrees, and the included angle is 82 degrees, making it suited for standard countersink work. With an overall length of 3.5 inches and a bright polished finish, this tool is built for precision metalworking applications where tool life and surface finish matter. Right-hand cutting direction is standard for conventional machine spindle rotation.

This combo drill countersink is used in metal fabrication, machining, and maintenance shops where operators need to create a clearance hole and countersink in one operation. The plain cutting edge style and non-tapered, non-aircraft geometry indicate general-purpose countersinking work on ferrous and non-ferrous metals. It is suited for use in CNC machining centers, drill presses, and manual mills. The double-end type provides extended tool life by offering two usable ends before replacement.

Key Features

• Solid carbide construction for wear resistance and long tool life in hard materials
• Drill and countersink in a single operation, reducing setup time
• 118-degree drill point angle for standard metalworking applications
• 82-degree included angle for consistent countersink geometry
• Bright polished finish reduces friction and aids chip evacuation
• Double-end design extends service life before replacement

Compatibility

Designed as a general-purpose combo drill countersink for use in CNC machining centers, drill presses, and milling machines operating with standard right-hand spindle rotation on ferrous and non-ferrous metal workpieces.

Installation Notes

This tool is installed and used by machinists and tool-and-die professionals in machine shop environments. Secure the shank firmly in a collet or drill chuck rated for the body diameter before operation. Verify spindle rotation is set to right-hand before engaging the tool. Use appropriate cutting fluid for the workpiece material to extend carbide tool life and maintain surface finish quality.
